A Method for Equipotential Operation of Conductors Arranged Vertically in Multiple Circuits

Abstract

The invention discloses a method for equipotential operation capable of entering multi-loop vertically arranged wires, and aims to provide a method for equipotential operation with high operation efficiency. The method includes the following steps: (1) the UAV uses an insulating pull plate connected with a hook to hang the dump block on the overhead ground wire; (2) hang the hanger on the wire through the insulating rope on the tip block; (3) Fasten one end of the insulating rope to one of the pulleys at the bottom of the hanger through the hanger. The insulating rope passes through the hanger and the hanging basket in the middle, and then passes through another pulley at the bottom of the hanger to form a pulley combination; the ground electrician Use an electric winch to pull the insulated rope, hang the hanger and the hanging basket to the working phase, and the equipotential operator sits in the hanging basket, and uses the potential transfer rod to carry out the potential transfer rod when it is close to the working phase; (4) When the operation is over, first put the hanger and the hanging basket on the ground, then lower the hanger, and finally drop the dump block from the overhead ground.

Description

technical field [0001] The invention relates to the technical field of power grid maintenance, in particular to a method for equipotential operation capable of entering multi-loop vertically arranged conductors. Background technique [0002] In the live overhaul process of transmission lines, using the ladder method to enter the strong electric field for equipotential work is the most commonly used method in China at present. Using this method to work has the following problems: [0003] (1) The physical energy consumption of the operators is high, and the requirements for the physical fitness of the operators are extremely high; [0004] (2) There are limitations in the scope of work, and it is not possible to enter the electric field through the ladder method on vertically arranged and multi-circuit lines; [0005] (3) The operation method is cumbersome, and it is difficult to throw the rope when hanging the ladder; [0006] (4) The operation risk is high. [0007] In o...

Problems solved by technology

[0003] (1) The physical energy consumption of the operators is high, and the requirements for the physical fitness of the operators are extremely high;

[0004] (2) There are limitations in the scope of work, and it is not possible to enter the electric field through the ladder method on vertically arranged and multi-circuit lines;

[0005] (3) The operation method is cumbersome, and it is difficult to throw the rope when hanging the ladder;

[0006] (4) High operational risk

[0007] In order to solve these problems and meet the requirements of multi-circuit and vertically arranged wire equipotential operation, and overcome the difficulties that the equipotential operators consume too much energy when climbing the ladder and the ladder method cannot meet the inter-phase combination gap, there is an urgent need for a multi-circuit vertical arrangement. The method of wire equipotential operation to meet the development needs of live work, reduce operation risk and improve work efficiency
